EDUs - Support buildings, Casitas & RV Garages

Custom Support Structures Designed for Modern Arizona Living


At Matson Homes, we specialize in designing and building high-quality support buildings, including Educational Dwelling Units (EDUs), casitas, and RV garages. With over 20 years of experience serving homeowners in Surprise and Peoria, Arizona, we understand how to create functional, stylish, and durable additions that complement your existing property. These structures enhance both your lifestyle and property value while addressing specific space and utility needs.


EDUs, often used as flexible support units, provide ideal accommodations for guests, extended family, or rental opportunities. Casitas offer private, detached living quarters perfect for in-laws or visitors, while RV garages protect recreational vehicles from the Arizona sun and dust. Each build is tailored to local codes, regional climate conditions, and your unique preferences. We use premium materials, experienced craftsmanship, and detailed planning to ensure each project aligns with your goals and the overall character of your home.

Our EDU, Casita & RV Garage Services

Educational Dwelling Units (EDUs)

EDUs are compact, self-contained support structures often used as secondary living spaces. Whether intended for multi-generational housing, private offices, or rental income, our EDUs are designed for versatility, privacy, and long-term functionality. We ensure each unit meets local zoning requirements and blends seamlessly into the primary residential property.

Custom Casitas

Casitas offer private, detached living quarters that are perfect for hosting guests or accommodating extended family members. Our team designs each casita to feel like a true home, complete with living areas, bathrooms, and kitchenettes. These structures provide added flexibility while maintaining visual harmony with the main residence.

RV Garages

Our RV garages are designed to accommodate large recreational vehicles while offering storage for other equipment and gear. Built with high clearances, reinforced doors, and weather-resistant materials, these garages provide optimal protection from Arizona’s intense heat, UV exposure, and dust. We also integrate workspace or utility options as needed.

Multi-Use Support Buildings

We build support structures that combine functions, such as a garage with an upstairs studio or a casita with storage space. These multi-use designs maximize square footage and increase property value. Our team works closely with clients to develop creative, efficient layouts that address both present and future needs.

Built for Lifestyle, Space, and Long-Term Value

At Matson Homes, we understand the importance of creating additional spaces that feel both functional and intentional. Whether you need a flexible living unit, a quiet guest retreat, or secure storage for your RV, our team delivers durable, attractive structures tailored to your needs. With deep roots in Surprise & Peoria, Arizona, and a commitment to excellence, we take pride in every build. Our support buildings are more than just add-ons—they’re strategic investments in your property’s comfort, functionality, and future value. Let us help you expand with purpose and confidence.
